1) Message boards : Prime Sierpinski Problem : WU's completed, marked as invalid. 0 credit. (Message 125307)
Posted 116 days ago by Janita
I found a lost PSP-result file in my primegrid folder (January, 5th, 2019). It is marked as erroneous in my results list. There was apparently some upload issue. Is there still any use for it? (Maybe too late to ask but the task has not yet been validated...)
The content of the file named llrPSP_308585931_0_r359405060_0 is
152267*2^20240619+1 is not prime. Proth RES64: C10A352AEFA3242A Time : 181301.255 sec.
2) Message boards : The Riesel Problem : TRP LLR Discussion (Message 90248)
Posted 1260 days ago by Janita
Is there a reason why the prime candidates that have been tested are not longer displayed at the results? Until a week ago or so there was always a line like "123456*2^123456-1 is not prime." (same happened to SR5 and probably also others). I would love to see them again to satisfy my curiosity...

I'd like to know how many prime factors have been found during the challange and maybe also how many candidates have been removed from the primality test list for the near future, say, for the llr-tests that we can expect to be run within the next year or between the current n (~8,200,000) and n=10.000.000. As I understand the sieving goes much further than 10.000.000. Thank you!

Is there a chance that we get also some numbers about eliminated prime candidates? I have run more than 600 tasks and found only one prime factor (and I do not know for which sub-project SoP, PSP, or ESP). Thanks!

I guess the next primes should have been found for 97768*5^n-1 and 130484*5^n-1.

It is already on the SR5-description page including a link to the prime database:
55154*5^1063213+1 found by Senji Yamashita on 16 June 2013

These two k's have already been greyed for a while on the SR5 welcome page (http://www.primegrid.com/forum_thread.php?id=5087).

I would bet a prime has been found for 243686*5^n-1. On the stat page it looks peculiar as it does not get new candiates to be tested.

If only one k would be pushed forward I would prefer 9221 as those tests run significantly faster on my computers.
